Help text

LOOKFOR Keyword search through the HELP entries.
	LOOKFOR XYZ looks for the string XYZ in the first comment line
	(the H1 line) of the HELP text in all M-files found on MATLABPATH.
	For all files in which a match occurs, LOOKFOR displays the H1 line.

	For example, "lookfor inverse" finds at least a dozen matches,
	including the H1 lines containing "inverse hyperbolic cosine"
	"two-dimensional inverse FFT", and "pseudoinverse".
	Contrast this with "which inverse" or "what inverse", which run
	more quickly, but which probably fail to find anything because
	MATLAB does not ordinarily have a function "inverse".

	LOOKFOR XYZ -all  searches the entire first comment block of
	each M-file.

	In summary, WHAT lists the functions in a given directory,
	WHICH finds the directory containing a given function, and
	LOOKFOR finds all functions in all directories that might have
	something to do with a given key word.

	See also DIR, HELP, WHO, WHAT, WHICH.
